Completing the application form

This page provides details of how to fill in the registration application form B(OTA). Before you fill in the application form you should read the information on eligibility to make sure you meet the requirements. If your application is rejected because you do not meet the requirements your fee will not be refunded.

You should fill in the form in block capitals using a black or dark-blue pen. Please enter all dates as dd-mm-yyyy, for example 29-04-2000.

If you would like help completing the application form you may use the services of a solicitor or other adviser. You should make sure the adviser you use is registered with the Office of the Immigration Services Commissioner (OISC).

If you would like to make sure you have completed your form correctly, many local authorities in the United Kingdom run a nationality checking service. For a small fee the authority will check your completed form, supporting documents and application fee before sending your application on to us for consideration.

You do not need to fill in all parts of the application form. The parts you need to complete will depend on the basis of your application. You should read the Guide B(OTA), which explains which parts you need to complete if you are:

  • applying on the basis of residence in the United Kingdom;
  • applying on the basis of Crown or similar service;
  • applying under the alternative provisions for British overseas territories citizens; or
  • under the age of 18 when you apply.
